Fake Dynamic Tree Shadows
An article by 
Tree shadows are created for terrain trees in Startup(),
with adjustable strength, shadow shape, shadow color etc. (unity indie)
Ideas/Todo:
– Animated shadow? (based on terrain wind settings or just random..?)
– Different shadows for different trees (Get treesize, type..)
– Angled shadows (currently its directly from up..)
– Shadow rotation with day cycle?
– Splat shadow or darker terrain texture also.
Features:
– Currently it only adds 9 drawcalls (doesnt matter how many trees you have)

Looks nice, looking forward to the future improvements. How does it work? With projectors?
Yes, using projector.
I got tree shadows (once) by flagging ‘hard shadows’ on my directional light, but I’d like a backup
plan, can you post the source please?
